BRAKES COMPLETELY FAILED AND I REAR ENDED A CAR. I WAS STOPPING NORMALLY ON A CITY STREET. ACCORDING TO DASHCAM I WAS TRAVELING AT ABOUT 25MPH. THE CAR SLOWED TO ABOUT 12MPH WHEN THE BRAKES WENT DOWN TO THE FLOOR AND THE CAR ACCELERATED.

ON A WINTER DAY MY CAR SLID DOWN A STEEP ROAD AND WOULD NOT STOP WHILE BREAKING, BOTH FRONT FENDER FLARES BROKE OFF CAUSING THE CAR TO ACT LIKE IT WAS ON A SLED. THE CAR EVENTUALLY STOPPED AFTER I PLACED IT IN NEUTRAL AND THEN SLID AGAIN AND THEN IT FINALLY STOPPED. I ALMOST KILLED MYSELF.

SUDDEN UNINTENDED ACCELERATION. 2014 PRIUS WAS PARKED FOR A FEW DAYS IN HOT, HUMID WEATHER. WHEN PULLING THE CAR INTO THE DRIVEWAY AT A LOW SPEED, THE CAR SUDDENLY ACCELERATED TO A VELOCITY FAST ENOUGH TO COLLIDE WITH AN SUV PARKED IN THE DRIVEWAY, KNOCKING IT THROUGH A METAL FENCE AND INTO THE BACKYARD. IT ALSO CAUSED THE DRIVER OF THE PRIUS WHIPLASH AND A HEAD INJURY. THE BRAKE PEDAL WAS DEPRESSED AS THE CAR ACCELERATED. WE BELIEVE THAT THE CAR ONLY STOPPED ACCELERATING WHEN THE RADIATOR WAS PUSHED INTO THE ENGINE BY THE IMPACT WITH THE BUMPER OF THE SUV.

I WAS PULLING INTO A CONVENIENCE STORE IN MY 2014 PRIUS. AS I WAS GLIDING IN, I DEPRESSED THE BRAKE PEDAL AND THE CAR KEPT GOING. I CONTINUED TO PRESS IT AND THE CAR STARTED TO ACCELERATE, I COULD FEEL THE SURGE OF POWER. I WAS COMPLETELY UNABLE TO STOP THE CAR AND RAN INTO PARKING POSTS AT THE FRONT OF THE STORE. ALL AIRBAGS WERE DEPLOYED. I GOT A CUT ON MY FOREHEAD, AN AMBULANCE CAME BUT I DECLINED AND MY HUSBAND DROVE ME TO THE ER LATER WHERE I RECEIVED TREATMENT. I WAS COMING HOME FROM THE GYM AT 9 AM I HAVE NEVER BEEN AT FAULT IN AN ACCIDENT BEFORE. I HAVE A WITNESS THAT SAID HE HEARD A CHIRPING SOUND COMING FROM THE BRAKES BEFORE I CRASHED. TOYOTA COMPLETELY DENIES THERE IS ANYTHING WRONG WITH THE CAR, BUT GIVES NO EXPLANATION AS TO HOW THIS COULD HAVE OCCURRED. THEY WILL NOT HELP AT ALL. SOMEONE IS GOING TO GET SERIOUSLY INJURED OR KILLED. THIS NEEDS TO BE INVESTIGATED BY SOMEONE OTHER THAN TOYOTA. *TR

I WAS PULLING INTO A CONVENIENCE STORE IN MY 2014 PRIUS. AS I WAS GLIDING IN, I DEPRESSED THE BRAKE PEDAL AND THE CAR KEPT GOING. I CONTINUED TO PRESS THE BRAKE AND THE CAR STARTED TO ACCELERATE. I COULD FEEL THE SURGE OF POWER. I WAS COMPLETELY UNABLE TO STOP THE CAR AND I RAN INTO PARKING POSTS AT THE FRONT OF THE STORE. ALL AIRBAGS WERE DEPLOYED. I GOT A CUT ON MY FOREHEAD AND WAS BLEEDING. AN AMBULANCE ARRIVED AND MY HUSBAND DROVE ME TO THE ER AFTERWARDS AND I RECEIVED TREATMENT. I WAS COMING HOME FROM THE GYM AT 9AM IN THE MORNING. I HAVE NEVER BEEN AT FAULT IN AN AUTO ACCIDENT BEFORE. I HAVE A WITNESS THAT SAID HE HEARD A CHIRPING SOUND COMING FROM MY BRAKES RIGHT BEFORE THE CRASH. I HAVE THE PIN DRIVE FROM THE CAR THAT A REPRESENTATIVE, SUPPOSEDLY FROM AN OUTSIDE SOURCE, THAT RETRIEVED IT. THIS IS WHAT TOYOTA USED TO CONDUCT THEIR "INVESTIGATION" INTO THE INCIDENT. THEY CONCLUDED THAT IT WAS COMPLETELY NOT THEIR FAULT, NOT INDICATING HOW IT COULD HAVE HAPPENED. THEY ARE NOT GOING TO HELP AT ALL. SOMEONE OTHER THAN TOYOTA NEEDS TO INVESTIGATE THIS PROBLEM BEFORE SOMEONE ELSE GETS KILLED. ( I FILED A PREVIOUS COMPLAINT THIS MORNING BUT REALIZED I HAD ENTERED THE VIN NUMBER WRONG. THIS IS THE SAME COMPLAINT WITH THE CORRECT VIN NUMBER. *TR

WHILE TRAVELING IN SLIPPERY CONDITIONS I ATTEMPTED TO NAVIGATE A RIGHT HAND TURN. THE CAR BEGAN TO SLIDE WHILE BRAKING INDICATING POSSIBLE SNOW BUILDUP IN FRONT OF TIRES. I ATTEMPTED TO ACCELERATE OUT OF THE SLIDE WHICH IS PROPER IN FRONT WHEEL DRIVE VEHICLES. THE CARS DASH LIGHTS LITE UP AND THE SLIDE INDICATOR STARTED BEEPING. THE CAR BECAME COMPLETELY UNRESPONSIVE TO THE GAS PROVIDING NO POWER WHATSOEVER. THE CAR SLID OVER THE CURB AND CRASHED INTO A HIGHWAY SIGN AND FINALLY CAME TO REST. *TR
